Abstract
The invention discloses a kind of light guide structure of car gear panel, including LED light source, light guide and gear character cover, the LED light source that on described gear character cover, kinds of characters is corresponding different, the light of different LED light sources is transmitted on gear character cover by light guide；It is arcuate structure between light incident side and the luminous reflectance end of described light guide, by arcuate structure at the formation reflecting curved surface within light guide.The invention have the benefit that the problem that light guide can solve intensity loss and lack of homogeneity that designs on light source, one utilizes refraction and the principle of reflection of light, light is penetrated and is conducted by being refracted into inside light guide at light guide incidence surface, thus can collect and make use of the light of major part loss originally, thus reaching to increase the purpose of brightness.It makes the light conducted in the inside of light guide constantly reflect, finally presents the exiting surface of a brightness uniformity two also with the principle of reflection of light, the reflecting curved surface of design light guide.
Description
Technical field
The present invention relates to automobile gears panel, particularly relate to and a kind of meet high brightness, brightness uniformity, light the light guide structure of car gear panel that area is bigger.
Background technology
At present, the mode that the light guide structure of automobile gears panel is light source direct projection lights character, during light source direct projection, its lighting angle is commonly greater than transmission region, formation light source loss district on transmission region both sides, causing that the brightness of light on gear character is not high, when extraneous light is strong, automobile gears is difficult to be revealed；On the other hand the light guide structure of light source direct projection is poor at the brightness uniformity of transmission region, generally presents central area high brightness, and the problem successively decreased gradually in past side.
Summary of the invention
The goal of the invention of the present invention is to solve above-mentioned technical problem, it is provided that a kind of light guide structure of car gear panel that can meet automobile gears panel high brightness and uniformity backlighting requirements.
In order to realize foregoing invention purpose, the technical solution adopted in the present invention is:
A kind of light guide structure of car gear panel, including LED light source, light guide and gear character cover, the LED light source that on described gear character cover, kinds of characters is corresponding different, the light of different LED light sources is transmitted on gear character cover by light guide；
It is arcuate structure between light incident side and the luminous reflectance end of described light guide, by arcuate structure at the formation reflecting curved surface within light guide.
Wherein, the radius of described reflecting curved surface is more than the twice of light guide thickness.
In order to realize the illumination effect of higher luminosity or multiple color, the present invention optimizes the light incident side of described light guide further and is provided with two or more planes of incidence, and described LED light source is correspondingly provided with two or more LED light emitting diode.
In order to reduce the loss of light, the present invention optimizes further, and described LED light emitting diode is close to the plane of incidence of described light guide.
The invention have the benefit that 1, solve intensity loss problem.Utilizing refraction and the principle of reflection of light, light is penetrated and is conducted by being refracted into inside light guide at light guide incidence surface, thus can collect and make use of the light of major part loss originally, thus reaching to increase the purpose of brightness.2, the problem solving brightness uniformity difference.Also with the principle of reflection of light, the reflecting curved surface of design light guide, make the light conducted in the inside of light guide constantly reflect, finally present the exiting surface of a brightness uniformity.3, the LED light source of different colours diverse location can be thrown in appointment position.
Accompanying drawing explanation
Fig. 1 is the structural representation of light guide structure of car gear panel of the present invention.
Wherein:
1:LED light source；2: light guide；3: gear character cover.
Detailed description of the invention
By describing the technology contents of the present invention, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Please generally consult Fig. 1, as shown in the figure, light guide structure of car gear panel of the present invention, including LED light source 1, light guide 2 and gear character cover 3, light guide 2 is arranged between gear character cover 3 and LED light source 1, the LED light source 1 that on described gear character cover 3, kinds of characters is corresponding different, the light of different LED light sources 1 is transmitted on gear character cover 3 by light guide 2；Described light guide 2 is arc light guide, is namely arcuate structure between light incident side and the luminous reflectance end of light guide 2, by arcuate structure at the formation reflecting curved surface within light guide 2.The present invention utilizes refraction and the principle of reflection of light, and light is penetrated and conducted by being refracted into inside light guide at light guide incidence surface, thus can collect and make use of the light of major part loss originally, thus reaching to increase the purpose of brightness.Also with the principle of reflection of light, the reflecting curved surface of design light guide, make the light conducted in the inside of light guide constantly reflect, finally present the exiting surface of a brightness uniformity.
In the present embodiment, the radius of described reflecting curved surface is more than the twice of light guide thickness, and within the scope of this, light guide effect is good, and fiber-loss is minimum.In the present embodiment, in order to realize higher luminosity and more various illumination effect, the present invention optimizes the light incident side of described light guide further and is provided with two or more planes of incidence, and described LED light source is correspondingly provided with two or more LED light emitting diode.Simultaneously in order to reduce the loss of light, the present invention optimizes further, and described LED light emitting diode is close to the plane of incidence of described light guide, and wherein LED light emitting diode is paster LED light emitting diode.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in the scope of patent protection of the present invention.
